the present article will address the potential for bronchial thermoplasty to be used in addition to conventional medications to help us treat our patients with severe asthma. ⋯ bronchial thermoplasty represents a novel approach to asthma treatment that is complementary to anti-inflammatory and bronchodilating therapies. Criteria for selecting appropriate patients are established and experience with bronchial thermoplasty is expanding since US Food and Drug Administration approval was obtained in April 2010.

This article reviews current data on pathophysiologic mechanisms by which sleep-disordered breathing during pregnancy may cause harm, and explores biological pathways for associated adverse maternal and fetal outcomes, especially pregnancy-induced hypertension and gestational diabetes. ⋯ Sleep-disordered breathing and adverse maternal-fetal outcomes such as preeclampsia and gestational diabetes share a number of mechanistic pathways, and growing data in pregnant women indicate that snoring and sleep apnea increase the risk of these and other complications for both the mother and the fetus. Nevertheless, direct evidence of the pathophysiologic mechanisms by which sleep-disordered breathing during pregnancy exerts negative effects remains sparse.

Recent literature on Aspergillus fumigatus infection and allergy in cystic fibrosis have expanded our understanding of many aspects of allergic bronchopulmonary aspergillosis, and bring new attention to A. fumigatus airways infection and A. fumigatus allergy without allergic bronchopulmonary aspergillosis (ABPA). ⋯ Diagnosis of CF-ABPA remains difficult, but improvements in serologic assays are occurring. Treatment remains in many cases unsatisfactory, and new agents offer promise but await proper controlled trials of safety and efficacy. A. fumigatus airway infection and A. fumigatus allergy without ABPA are emerging as further complications of A. fumigatus respiratory colonization in patients with CF, but prospective studies are needed to corroborate largely retrospective findings.

Patients with obstructive sleep apnea (OSA), as well as their physicians, seek alternative therapies to continuous positive airway pressure (CPAP) due to problems with CPAP adherence. A large variety of surgical options exist, and each intervention must be individually evaluated. The author performed a literature search concerning surgery for sleep apnea until May 2010. The studies were evaluated according to evidence-based medicine criteria. ⋯ Patients who are nonadherent to CPAP must be thoroughly evaluated before choosing any of the available surgical options. Upper airway surgery may improve disease markers of OSA, if appropriately chosen and properly indicated and performed.

Neurosarcoidosis may be a serious complication of sarcoidosis. As the presentation of neurosarcoidosis is manifold, solitary nervous system sarcoidosis without systemic activity remains a difficult diagnosis. Appropriate treatment may be a dilemma. ⋯ In this paper an update on clinical manifestations of neurosarcoidosis, diagnostic dilemmas, and therapeutic options is provided.
